How to Build A High Pressure Aeroponics System? Follow these 5 steps

What is Aeroponics?

Are you looking for alternative ways of growing plants? I have always loved gardening, but due to lack of space had to restrict my choices. One day, I met a person who was using aeroponics to grow plants. It was exciting, and I started to research more about it. I soon realized that aeroponics is one of the types of hydroponic systems. It works on a simple concept, though it is probably more technical than the other methods. I have been tinkering around with high-pressure aeroponic systems for a long time and have achieved excellent results.


How To Build A High Pressure Aeroponics System

It is probably the best way to grow plants without soil. Plants are not contained or rooted in any solid material. The plants' roots hung in the air in an enclosed chamber and sprayed with a nutrient-rich solution or high-pressure mist. You can say that, instead of plants searching for nutrients in the soil, here, the nutrients are being delivered to the plants! The plants grow faster because they absorb the nutrients better. If you are keen on learning how to build a high pressure aeroponics system, then this article can help you and offer step by step, easy to follow the process.

Types of Aeroponic Systems

There are two types of aeroponic systems

Low-Pressure Aeroponics (LPA)

LPA is the most commonly used system because of the ease of setting it up and availability. It does not cost as much as an HPA system. The system has a standard pump combined with some tubes and sprinklers. The water comes out as reasonably large droplets which cover the plant roots. LPA systems generally run continuously throughout the day and keep the roots always wet. This system works well and is easy to build.

High Pressure Aeroponics (HPA)

HPA比LPA系统更复杂,并且需要更多的组件。除喷嘴,开关等外,您将需要一个坚固的泵和一个好的储罐,购买优质零件将确保更好的结果。 HPA会产生非常细的雾,这是由于压力造成的。根可以吸收更多的水分&营养液的速度更快,因为其尺寸很小。

Working of A High Pressure Aeroponic System



The secret to successful high-pressure aeroponics will depend on the right amount of oxygen and other nutrients reaching the plant via the roots.

What Do You Need to Build High Pressure Aeroponics System?

Are you ready to set up an HPA system? We can trace the design of HPA to the 1970s. However, it was only in the 1990s that NASA made it famous by proclaiming it an efficient way to grow plants in the space. It is a simple yet effective way to grow plants without soil. You will be able to grow healthier plants with this system. I have tried growing different types of plants and find them equally suited to vegetables and other plants. If you are ready to take the plunge, it is time to collect everything you need and understand the process fully.

Here is a list of things that you can procure easily from any local gardening store or even online. You can watch this video to understand different component functions.

  • Growing chamber: you should get an airtight and light-proof container. Only air should reach the roots and not pests or insects. Water should not spill out, and humidity should remain inside.
  • Container for Nutrient Solution: 这是任何HPA系统的重要组成部分。这些容器或罐已预先加压,可防止泵过热和过度工作。它们通常具有两个隔室并调节压力。
  • Pump: 该泵是任何HPA系统的心脏。它必须在正确的压力下产生正确大小的液滴。该泵必须定期产生80 psi的压力,因此您应该购买质量合适的泵。
  • Spray Nozzles: 泵以高压方式将水输送到喷嘴。水的雾化由于高压和小喷嘴而发生。小心选择雾状喷嘴,因为如果直接指向某一点,高压甚至会损坏根部。保持喷嘴清洁,并使用网状过滤器防止堵塞。
  • Solenoid: this is the coil of wire used to stop and start the water flow as per the timer settings. This is an electrically operated valve and works as an automatic lawn sprinkler.
  • Pressure Switch: 它告诉泵何时以及在什么压力下打开和关闭。有些泵带有此控制开关,而有些泵则需要单独购买。最好将压力设置为80 psi,关闭时为100 psi。
  • Tubes: you need rubber or PVC tubes to take the water from the nutrient pump to the spray nozzles.
  • Baskets/Platform: you need the right kind of baskets or any other platform with the right type of support for hanging the plants.
  • Timer: either an inbuilt timer or one bought separately is a must. It will accurately turn on and off the pump.

Apart from these things, you should ensure that you choose a convenient location for you to manage. There should be room around the chamber for you to move freely.

Steps for Building High Pressure Aeroponic System

Have you collected all the items listed here? Now, follow these steps to build your little garden without any hassle.

Step 1

The first step to do is to decide how much of the HPA system you are planning to build. You can get readymade containers and chambers, or you can choose to build it. You can use different materials like wood, plywood, or plastic containers lying around the house. The size will depend on the type and number of plants. It should have enough depth for the roots to hang and grow freely. There should be enough space for oxygen and CO2 to circulate.

Step 2

Depending on the material and weather, you can line the box with some insulating material like a plastic sheet or Styrofoam.

Step 3


Step 4

Now comes the most crucial part where you put all the components together. The basic working of any system will be as follows. The nutrient in the accumulator tank gets sucked into the pump, and then through the tubes goes to the spray nozzles. However, the working may differ from system to system depending on the type of kit, plants, and quality of components. Having a switch for pressure and timer will add to the accuracy.

Step 5

建立设置后,请在检查压力和液滴大小的同时进行彻底测试。形成雾的最低要求是80 psi的压力。购买圆锥形的喷嘴,以使雾气均匀扩散。计时器控制营养的供应和压力。对工作满意后,请确保将其牢固地固定在理想且合适的位置。

Things to Remember

  • Some essential things that you should keep in mind when you take on this project are your capabilities, money, time, and the plants you want to grow.
  • It is better to start small. As a beginner, you will be experimenting and learning, so don’t invest too much money initially.
  • Always buy the right quality components.
  • There are many kits available, and you can choose to ultimately build or assemble readymade kits depending on your skill level.

Some Pros and Cons Of High Pressure Aeroponic System

The best benefit of an aeroponic system is the higher yield and faster growth of plants. However, there are a few drawbacks as well, though the advantages far outweigh the disadvantages.


  • This system uses almost 90 % less water than conventional growing systems
  • You will require only about 1/3 rd of the nutrients in this method
  • Faster plant growth because roots are regularly exposed to oxygen
  • Higher yields and more harvest cycles possible
  • No growing medium so you don’t spend money on soil, and roots absorb all nutrition
  • By sterilizing the mist, you can prevent plant diseases
  • Easy to move the plants from one collar to another.
  • You don’t need much space. With a modular system, it is easy to maximize the use of small spaces
  • Quite easy to replace old plants with new ones
  • A great educational tool for kids to teach them about plants without getting them dirty


  • The initial investment for buying different components
  • Close monitoring and frequent maintenance is necessary
  • Even a short failure can lead to a loss of the whole crop
  • Technical knowhow of the system is essential and could be difficult for beginners
  • Any power outages can cause a problem
  • You will have to disinfect the chamber to prevent root disease regularly


Choose the Location Carefully

You must consider the placement of the system carefully otherwise it can hinder the growth of plants.

  • Light: if you can get natural light for about 8 hours, it will be perfect. Depending on the plant variety, you may need more or less light. You can add artificial lights if natural light is not enough.
  • Water: use distilled water as far as possible. As you will be adding nutrients to the water, you don’t want any contaminants.
  • Air: air movement is crucial. Stagnant air can be harmful to a plant’s growth.
  • Health& Hygiene: 设置系统之前,请对所有组件进行消毒。将植物和系统放在安全的地方。密切注意根部是否有任何有害生物迹象,并尽可能使用天然杀虫剂。
  • Temperature: plants don’t grow well at lower temperatures. A range between 70 degrees and 85 degrees is ideal for most plants.
  • Moisture: you have to be careful while setting the timer for spraying interval and duration. Different plants have different needs at each stage of their growth. Excess and less moisture, both are harmful.

Importance of The Nutrient Solution


  • This system uses very less water and nutrients, so use good quality water only
  • Hard water is not suitable for plants. It has calcium carbonate in high quantity which is difficult for plants to process
  • You must check the mineral concentration in the water as well check for good and bad minerals
  • The right pH level is essential. Most plants grow well between 6 and 7 pH levels. Buy nutrients which will help keep the pH level in this range
  • 空气和水中已经存在碳,氢和氧。除了这些,对于健康的植物,最好是含有磷,氮,钾,锌,硼,锰等。


Does all this information seem a bit overwhelming to you? I can understand because I was once in your position. Initially, it may seem complicated, but if you follow all directions, in no time, you will be reaping the benefits, literally! When I started, it wasn't easy to find the right information and high-quality components, but now both are available easily. It may seem too technical initially, but once you understand the working, rest is about joining the various tubes and connecting everything properly.

With experience, you can make the system thoroughly self- monitor itself. Depending on how technical you want to get, you can also collect a lot of data about light, humidity, moisture, etc. to ensure better plant health and faster yield.
